P-LNG, A Low Cost Liquefaction Process

Gas Transport Solutions Inc. is offering a new way to liquefy and transport natural gas. Using a combination of conventional (non-cryogenic) refrigeration, and moderate pressure, natural gas is easily liquefied. For safe storage, the pressurized-liquefied natural gas (P-LNG) is stored inside of our proprietary type-4 pressure vessels (tanks). For transport, our tanks are secured inside of standard ISO shipping containers. The assembly creates an intermodal transport module (ITM) that provides a very high-level of impact resistance. With an ITM, natural gas stored as P-LNG is safely transported/ exported using the world’s existing infrastructure; trucks, trains, and ships.

The practicality of our technology is due to the light weight nature of our large composite tanks. A fully loaded ITM will meet the road weight limitations of most roads and highways throughout North America and the world.

Our 40-ft ITM with three tanks will safely store approximately 10 metric tonnes (470 Mscf) of natural gas as P-LNG. With 4 tanks in a 53-ft ITM, approximately 13 MT of P-LNG is stored.

A preferred combination of pressure and temperature requiring minimal energy input would be around 90 Bar pressure at -50 C.

Using our proprietary process, the cost to liquefy and load our ITMs is less than $0.40 (CAN)/ GJ or MMBtu. Conventional LNG is currently above $4.00 / MMbtu and rising.

Our ITMs will provide for the direct delivery of natural gas to existing industrial and commercial markets. The intermodal delivery of natural gas will disruptively bypass utility providers and LNG terminals. Where there is no current gas provider, our ITMs will deliver new supplies of natural gas to help progress commercial and social development.

Our ITMs may also be used to rapidly discharge bulk natural gas into a distribution (utility) pipeline. ITMs are designed for rapid discharge, where needed.

Our ITMs will also provide safe fuel gas storage systems for ships and trains. Where bunkered LNG is available, the LNG is pumped up to 100 Bar and warmed up to -50 C using sea water. Our tanks are safe enough to be stored below deck, if desired.

Using lower pressure tanks, other gaseous fluids such as ethane, ethylene, CO2, propane, methanol, or ammonia may be safely transported as low-cost pressurized liquids.
